There was plenty of action on the iHeartRadio Music Festival stage on Friday night, but there was just as much going on backstage too.

We caught Taylor Swift, Ariana Grande, Jennifer Lawrence (minus boyfriend Chris Martin), Jason Derulo, Usher, Chris Brown, and more hanging out behind-the-scenes.

Check out the photos … and don’t forget to tune in to Night 2 of the iHeartRadio Music Festival on Saturday night at 10 p.m. ET / 7 p.m. PT here.
